Lash, whose 15-minute work, “Hush,” was heard at an ASO Classical Edge concert in October, will have her new work, an ASO commission titled “Nymphs,” premiered at the concerts, which start at 8 p.m. each night at the Alys Stephens Center. A member of the Yale University music faculty, Lash studied at the Eastman School of Music, Cleveland Institute of Music, Yale and Harvard University. Her music has been performed at Carnegie Hall, Le Poisson Rouge and the Tanglewood Music Center. In addition to ASO, she has received numerous commissions -- from the Fromm Foundation, Naumburg Foundation and the Aspen Music Festival, among others.

Grosvenor, a 21-year-old pianist from the U.K. who started collecting awards when he was 10, is the youngest-ever double Gramophone Award winner, taking the Instrumental Award and Young Artist Award in 2012. He records exclusively for Decca Records, including one with the Royal Liverpool Philharmonic of the same Saint-Saëns Concerto (No. 2 in G minor) that he will perform with ASO (listen to the video below). He performed the work at the BBC Proms in 2012, the Financial Times commenting that he “alternated between a distant dream world and outbreaks of sparkling effervescence.”

Among Grosvenor's solo engagements are those with the New York Philharmonic, Tokyo Symphony, Cleveland Orchestra, and Royal Philharmonic, with conductors such as Vladimir Ashkenazy, Jiří Bělohlávek, Semyon Bychkov and Andrey Boreyko.
